Stupid ideas should be bashed.

Just because some statement has the word "God" in front of it should not make it immune to criticism. To steal an idea from Douglas Adams, if you're going to tell me that you can't flip a light switch on Sunday, I'm going to say "that's stupid." Why is it, then, that if the statement is changed to "God says I can't flip a light switch on Sunday" that it is suddenly protected and barred from criticism?

That's ridiculous. Religion should not be shielded from criticism. If even mathematically proven theories are open for criticism, then something that has never even been proven should be equally open for criticism.
